8. Aggregate claims have been modeled by a compound negative binomial distribution with parameters $r = 15$ and $\beta = 5$. The amount of each loss has a Weibull distribution with parameters $\theta = 5$ and $\tau = 1/2$. Using the normal approximation, determine the premium such that the probability that claims will exceed premium is 0.05
